DRÄGER PAC 5500
DrägerSensors®
Dräger XXS Sensors provide longer operating times.
Large display
Clearly structured, language-free display shows all
necessary information at one glance.
Robust housing
Impact-resistance combined with an ergonomic design.
High visibility
Colored overlays are available to distinguish the instrument
at a distance.
Bringing maximum confidence to the
user, the instrument will also emit both
pre and main alarms before loss of battery
power. If there should be a problem with
the electronics or the battery or the
sensor, the user will receive a clear,
immediate fault alarm and display indica-
tion. A further "life signal" option, which
can be activated and/or disabled to suit
specific requirements, is also available.
BUMP TEST AND CALIBRATION
Bump Testing allows users to test equip-
ment against a known gas concentration
on a regular basis. Bump tests check that
instruments are functioning correctly.
Equipped with adjustable bump test and
calibration intervals to meet the needs of
different applications, the Dräger Pac
5500 displays a warning as soon as a
bump test or calibration is required.
Should the warning be ignored, the
instrument can automatically display an
"out of order" error message. As an option,
users can also select this same error
message to indicate that the calibration
interval has expired.
Bump tests usually take between 8 and
15 seconds and to ensure that they can
be performed quickly and easily, the
Dräger Pac 5500 can be used with the
Dräger Bump Test Station. This economi-
cal unit allows both the instrument and
sensor performance to be checked any-
where, without the need for additional
power. Each successful test is automati-
cally stored in the data logger. The user
can choose for failed tests to render the
instrument "out of order". An optional
mobile printer is also available for those
applications where hard copies are required,
and to store up to 700 tests for downloaded
to a PC.
Fresh air calibration can be performed
during the boot sequence at start up and
is easy to perform.
Calibration can be carried out by docking
the instrument to a PC, and an optional
automated test and calibration system is
also available. The recommended
inspection interval for Dräger Pac 5500
is 2 years.
EVENT LOGGER
Able to store up to 60 events complete
with dates and times, the Dräger Pac 5500
incorporates an IR interface and can be
easily linked to a PC via a connecting
cradle. As a result, significant events such
as switch on/off, gas and battery alarms,
